NAME

KinoSearch::Search::LeafQuery - Leaf node in a tree created by QueryParser.

SYNOPSIS

    package MyQueryParser;
    use base qw( KinoSearch::Search::QueryParser );

    sub expand_leaf {
        my ( $self, $leaf_query ) = @_;
        if ( $leaf_query->get_text =~ /.\*\s*$/ ) {
            return PrefixQuery->new(
                query_string => $leaf_query->get_text,
                field        => $leaf_query->get_field,
            );
        }
        else {
            return $self->SUPER::expand_leaf($leaf_query);
        }
    }

DESCRIPTION

LeafQuery objects serve as leaf nodes in the tree structure generated by QueryParser's tree() method. Ultimately, they must be transformed, typically into either TermQuery or PhraseQuery objects, as attempting to search a LeafQuery causes an error.
